[0054] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.
[0055] Reference below Figure 1-Figure 9 Describe the detection platform and detection device according to the embodiments of the present application.
[0056] The detection platform can be used to absorb and carry the product 7 to be detected, and drive the product 7 to be detected to rotate so as to detect the surrounding side of the product 7 to be detected.
[0057] The product to be inspected 7 may be a part such as a side or front side button, a screen, etc. in an electronic product.
[0058] like Figure 1 As shown, the detection platform of the embodiment of the present application includes: a platform 1, a rotation drive mechanism 2, a deformation connection mechanism 3, an adjustment mechanism 4 and a negative pressure component 5.
[0059] The carrier 1 has a suction nozzle 14 and a first air channel 15 connected to the suction nozzle 14 , and the carrier 1 is used for carrying the product 7 to be inspected.
[0060] The carrier 1 can be made of high-strength, low-deformation material, such as an aluminum alloy carrier or stainless steel, and its upper surface is designed to be a flat surface or a curved surface that conforms to the shape of the product 7 to be inspected to improve the stability of the product 7 to be inspected placed on the carrier 1.
[0061] like Figure 4 As shown, the carrier 1 is provided with one or more suction nozzles 14 , which are connected to the first air channel 15 . When the first air channel 15 is connected to an external negative pressure source, the suction nozzle 14 can generate a negative pressure adsorption force to adsorb the product 7 to be inspected onto the carrier 1 .
[0062] When one suction nozzle 14 is provided, the suction nozzle 14 may be provided at the center of the carrier 1 ; when multiple suction nozzles 14 are provided, the multiple suction nozzles 14 may be distributed in a centrally symmetrical manner about the center of the carrier 1 .
[0063] The carrier 1 is used to carry and fix the product 7 to be detected. The carrier 1 can reduce the movement of the product 7 to be detected during the detection process by negative pressure adsorption.
[0064] The rotation drive mechanism 2 includes a motor 21, a reducer, an output shaft 211 and a second air channel 23. The motor 21 drives the output shaft 211 to rotate through the reducer to achieve rotation adjustment of the carrier 1. The second air channel 23 is arranged inside the output shaft 211, and the second air channel 23 is used to transmit negative pressure.
[0065] The rotary drive mechanism 2 is used to provide rotary power so that the carrier 1 and the product to be inspected 7 thereon can rotate in a plane, so as to facilitate circumferential inspection of the product to be inspected 7 from multiple angles.
[0066] The adjusting mechanism 4 is coupled to the output shaft 211 of the rotating drive mechanism 2 and the carrier 1 , so that the carrier 1 , the adjusting mechanism 4 and the output shaft 211 of the rotating drive mechanism 2 can achieve synchronous movement.
[0067] The adjustment mechanism 4 and the carrier 1 can be coupled and connected by means of snap connection or threaded connection. Exemplarily, the adjustment mechanism 4 is provided with a groove, and the carrier 1 is snapped with the groove in a concave-convex matching manner. When the adjustment mechanism 4 rotates with the rotary drive mechanism 2, the adjustment mechanism 4 is snapped with the carrier 1 to transmit the rotational torque.
[0068] The adjustment mechanism 4 is adjustable along the axial direction of the output shaft 211 of the rotating drive mechanism 2, so that the position of the carrier 1 on the axial direction of the output shaft 211 of the rotating drive mechanism 2 can be adjusted, which is convenient for adjusting the axial position of the carrier 1, thereby improving the alignment effect between the carrier 1 and the imaging device and improving the detection effect of the product 7 to be detected.
[0069] The adjusting mechanism 4 is detachably connected to the output shaft 211 of the rotary driving mechanism 2 .
[0070] In this embodiment, the adjusting mechanism 4 is connected to different positions of the output shaft 211 of the rotary drive mechanism 2 to achieve the axial adjustment of the adjusting mechanism 4 along the output shaft 211 of the rotary drive mechanism 2 .
[0071] For example, the adjustment mechanism 4 and the output shaft 211 of the rotary drive mechanism 2 may be connected by means of a snap connection, a threaded connection or a clamping connection.
[0072] The two ends of the deformable connection mechanism 3 are coupled to the carrier 1 and the rotation drive mechanism 2 respectively. The two ends of the deformable connection mechanism 3 can be sealed with the carrier 1 and the rotation drive mechanism 2 by means of threaded connection, plug-in connection or clamping.
[0073] Two ends of the deformable connection mechanism 3 are connected to the first air channel 15 and the second air channel 23 respectively, and the deformable connection mechanism 3 is a hollow structure.
[0074] Exemplarily, at least a portion of the deformable connection mechanism 3 may be made of an elastic tube such as a rubber tube or a flexible tube, so that the length of the deformable connection mechanism 3 along the distribution direction of the first air channel 15 and the second air channel 23 is adjustable.
[0075] During the height adjustment or rotation of the carrier 1, the deformable connection mechanism 3 can improve the patency and airtightness of the connection between the first air channel 15 and the second air channel 23, while absorbing the stress generated by the axial height change or rotation of the adjustment mechanism 4 along the output shaft 211 of the rotating drive mechanism 2, thereby improving the air channel sealing and connection stability.
[0076] It should be noted that the carrier 1 is connected to the rotary drive mechanism 2 through the adjustment mechanism 4, the first air channel 15 and the second air channel 23 are connected through the deformable connection mechanism 3, and the length of the deformable connection mechanism 3 is related to the installation position of the adjustment mechanism 4 on the output shaft 211 of the rotary drive mechanism 2.
[0077] The negative pressure port of the negative pressure component 5 is connected to the second air channel 23. The negative pressure component 5 provides a stable negative pressure source for the carrier 1 so that the product 7 to be tested is firmly adsorbed on the carrier 1, reducing the risk of movement or falling off of the product 7 to be tested during the testing process.
[0078] According to the detection platform provided in the present application, the platform 1, the deformable connection mechanism 3, the adjustment mechanism 4 and the output shaft 211 of the rotating drive mechanism 2 are formed into a whole. During the rotation of the output shaft 211 of the rotating drive mechanism 2, the platform 1, the deformable connection mechanism 3 and the adjustment mechanism 4 rotate synchronously, and the first airway 15, the deformable connection mechanism 3 and the second airway 23 rotate synchronously. The deformable connection mechanism 3 can absorb the stress generated by the height change or rotation of the platform 1 and the output shaft 211 of the rotating drive mechanism 2, thereby improving the airway sealing and the stability of the connection, avoiding the phenomenon of airway winding, and reducing the risk of air leakage.
[0079] like Figure 4 and Figure 7 As shown, in some embodiments, the deformable connection mechanism 3 includes a first joint 31, a second joint 32 and a deformable tube connected between the first joint 31 and the second joint 32, and the first joint 31 and the second joint 32 are sealed and connected to the carrier 1 and the rotation drive mechanism 2 respectively.
[0080] Exemplarily, the first joint 31 and the second joint 32 may be sealedly connected to the carrier 1 and the rotary drive mechanism 2 by means of threaded connection, plug-in connection, flange connection, or the like.
[0081] The first connector 31 may be designed to have a shape and size that matches the first air channel 15 on the carrier 1. Exemplarily, the first connector 31 may be made of metal or high-strength plastic to improve the stability and durability of the connection.
[0082] A sealing structure is provided between the first connector 31 and the first air channel 15 . Exemplarily, the sealing structure may be an O-ring or a metal sealing ring, so as to form a sealed connection between the first connector 31 and the first air channel 15 .
[0083] The design of the second joint 32 is similar to that of the first joint 31, but the size and shape of the second joint 32 must match the second air passage 23 of the rotary drive mechanism 2. Similarly, a sealing structure is also provided between the second joint 32 and the second air passage 23 to ensure a tight connection between the second joint 32 and the second air passage 23 and reduce gas leakage.
[0084] The deformable tube is connected between the first joint 31 and the second joint 32 . The deformable tube can be made of an elastic material and has excellent flexibility and corrosion resistance.
[0085] Exemplarily, the deformable tube may be a rubber tube, a silicone tube, a thermoplastic elastic tube, or the like.
[0086] The deformable tube can be deformed when subjected to external force. The change in the distance between the first joint 31 and the second joint 32 can generate tension or pressure on the deformable tube, thereby causing the length of the deformable tube to deform, thereby absorbing the stress and displacement caused by the height adjustment or rotation of the carrier 1 while maintaining the patency of the airway.
[0087] The length and diameter of the deformable pipe can be customized according to actual needs to meet the requirements of different application scenarios.
[0088] In this embodiment, when the stage 1 is height-adjusted or rotated by the adjustment mechanism 4, the deformable tube can be deformed to adapt to the relative movement between the stage 1 and the rotation drive mechanism 2. This deformation not only keeps the airway unobstructed, but also reduces the risk of connection failure or gas leakage due to stress concentration. The design of the deformable connection mechanism 3 enables it to maintain stable performance during long-term use, and maintain good sealing and durability even in harsh working environments.
[0089] In some embodiments, Figure 5 , Figure 6 and Fig. 9 As shown, the carrier 1 includes an adsorption block 11 and a connecting portion 12 distributed along the axial direction. The adsorption block 11 and the connecting portion 12 can be connected by integral molding, welding, or threaded connection.
[0090] The suction block 11 has a suction nozzle 14 and a first air passage 15 .
[0091] A suction nozzle 14 is provided at the center of the adsorption block 11 , and the suction nozzle 14 is connected to a first air channel 15 . When the first air channel 15 is connected to an external negative pressure source, a negative pressure adsorption force can be generated to fix the product 7 to be detected.
[0092] The two ends of the connection part 12 are respectively connected to the adsorption block 11 and the adjustment mechanism 4, and the connection method can be threaded connection, snap connection, flange connection or other reliable connection methods. The adjustment mechanism 4 is connected to the adsorption block 11 through the connection part 12 to achieve precise adjustment of the position of the carrier 1.
[0093] The connecting portion 12 is located at two sides or the bottom of the adsorption block 11 , and the extending direction of the connecting portion 12 is consistent with the axial direction of the carrier 1 .
[0094] Taking the axial direction of the carrier 1 as the projection direction, the projection of the connecting portion 12 is radially located on both sides of the projection of the first air duct 15 . The connecting portion 12 will not interfere with the connection and use of the first air duct 15 . At the same time, this layout also helps to improve the overall stability and carrying capacity of the carrier 1 .
[0095] In some embodiments, Figure 8 As shown, the adjustment mechanism 4 includes an adjustment member 41 and a fastener 42 .
[0096] The adjusting member 41 includes a first portion 411 and a second portion 412 connected to each other. The first portion 411 forms a first avoidance hole 4111 for avoiding the deformable connection mechanism 3. The avoidance hole is designed to reduce interference or damage to the deformable connection mechanism 3 when adjusting the position of the carrier 1. The shape and size of the first avoidance hole 4111 need to match the shape of the deformable connection mechanism 3 to provide enough space for it to pass through.
[0097] The second portion 412 includes a first deforming portion 4121 and a second deforming portion 4122 , and the first deforming portion 4121 and the second deforming portion 4122 are located at two sides of the output shaft 211 of the rotary drive mechanism 2 in the radial direction.
[0098] The first deformation portion 4121 and the second deformation portion 4122 may be made of an elastic material. Exemplarily, the first deformation portion 4121 and the second deformation portion 4122 may be spring steel, rubber or silicone. The first deformation portion 4121 and the second deformation portion 4122 have excellent flexibility and corrosion resistance.
[0099] When adjusting the position of the carrier 1, the first deformation portion 4121 and the second deformation portion 4122 can be deformed to approach each other so as to clamp and fix the output shaft 211 of the rotating drive mechanism 2, or the first deformation portion 4121 and the second deformation portion 4122 can be deformed to move away from each other so as to loosen the output shaft 211 of the rotating drive mechanism 2 to achieve the disassembly of the adjustment mechanism 4 and the output shaft 211 of the rotating drive mechanism 2.
[0100] The fastener 42 is connected to the first deforming portion 4121 and the second deforming portion 4122 respectively so that the first deforming portion 4121 and the second deforming portion 4122 are detachably connected to the output shaft 211 of the rotary drive mechanism 2 .
[0101] Exemplarily, the fastener 42 may be a bolt, a nut, a buckle or other reliable connector. Through the fastener 42, the spacing between the first deformable portion 4121 and the second deformable portion 4122 may be adjusted, thereby achieving the clamping or loosening of the first deformable portion 4121 and the second deformable portion 4122.
[0102] In some embodiments, Figure 5 As shown, the rotation driving mechanism 2 includes: a motor 21 , a light shielding sheet 22 and a position sensor 24 .
[0103] An output shaft 211 of the motor 21 is coupled to the adjusting mechanism 4 .
[0104] The motor 21 is the power source of the rotation drive mechanism 2, and can be a stepper motor or a servo motor, for example, to achieve precise rotation control of the stage 1. The output shaft 211 of the motor 21 is coupled to the adjustment mechanism 4 to drive the stage 1 to rotate by transmitting torque.
[0105] The shading sheet 22 is coupled to the output shaft 211 of the motor 21 . The shading sheet 22 and the output shaft 211 of the motor 21 may be fixed by a keyway, a pin or other reliable connection methods.
[0106] The shading sheet 22 is designed to mark the position of the stage 1, and the shape and size of the shading sheet 22 need to match the detection range of the position sensor 24. During the rotation of the stage 1, the shading sheet 22 will rotate accordingly, thereby changing the shielding of the optical path of the position sensor 24.
[0107] The position sensor 24 is arranged on the rotation track of the shading sheet 22. The position sensor 24 cooperates with the shading sheet 22. When the shading sheet 22 rotates to a specific position, the shading sheet 22 blocks or changes the optical path or magnetic field of the position sensor 24, thereby triggering the output signal of the position sensor 24. This signal can be used by the control system to determine whether the stage 1 is located at the initial position or other preset positions.
[0108] Exemplarily, the position sensor 24 may be a Hall sensor, a magnetoresistive sensor, a photoelectric sensor, or a proximity switch.
[0109] In actual use, before starting the rotation drive mechanism 2, the position sensor 24 is in an unblocked state (or a specific magnetic field state), and the position sensor 24 outputs a low level (or a specific voltage value) signal. When the motor 21 starts and drives the carrier 1 to rotate, the shading sheet 22 rotates accordingly. When the shading sheet 22 rotates to the initial position, the shading sheet 22 will block the optical path of the position sensor 24 (or change the magnetic field), triggering the output signal of the sensor to become a high level (or a specific voltage value). After the control system detects this signal change, it can be determined that the carrier 1 has reached the initial position and stop the rotation of the motor 21.
[0110] During the detection process, the control system can send a rotation command to the motor 21 as needed to control the stage 1 to rotate to a specific angle. After the motor 21 receives the command, the output shaft 211 of the motor 21 rotates and transmits the torque to the stage 1 through the adjustment mechanism 4. At the same time, the light shielding sheet 22 will also rotate with the output shaft 211, changing the shielding of the optical path of the position sensor 24. The control system can determine the current position of the stage 1 by monitoring the output signal of the position sensor 24, and make fine adjustments or stop the rotation as needed.
[0111] Due to the cooperation between the light shielding sheet 22 and the position sensor 24, the rotary drive mechanism 2 can realize accurate control and feedback of the position of the stage 1. This design not only improves the accuracy and efficiency of the detection, but also enhances the stability and reliability of the detection stage.
[0112] In some embodiments, Figure 4 As shown, the detection platform includes multiple platforms 1, multiple rotation drive mechanisms 2, multiple deformation connection mechanisms 3 and multiple adjustment mechanisms 4. The multiple platforms 1, multiple rotation drive mechanisms 2, multiple deformation connection mechanisms 3 and multiple adjustment mechanisms 4 are arranged one by one, so that multiple platforms 1 can work at the same time and perform parallel detection. This greatly improves the detection efficiency and shortens the detection cycle.
[0113] The number of the carriers 1 may be 4 to 12. For example, the number of the carriers 1 may be 5, 8 or 11.
[0114] The negative pressure assembly 5 includes a negative pressure generator 51, a main pipe 52 and a plurality of branch pipes 53. The negative pressure generator 51 is the power source of the negative pressure assembly 5 and is used to generate a stable negative pressure airflow. Exemplarily, the negative pressure generator 51 can be a vacuum pump, a fan or other equipment capable of generating negative pressure.
[0115] The main pipe 52 is the main channel of the negative pressure airflow, and the main pipe 52 connects the negative pressure port of the negative pressure generator 51 and the multiple branch pipes 53. The design of the main pipe 52 needs to ensure sufficient flow and pressure to meet the requirements of all the carriers 1 working simultaneously. The main pipe 52 can be a branch block.
[0116] The negative pressure port of the negative pressure generator 51 is connected to the main pipe 52, and multiple branch pipes 53 are connected to the main pipe 52 in parallel. The multiple branch pipes 53 are respectively connected to multiple second air channels 23 one by one to introduce negative pressure airflow into the surface of the carrier 1 to adsorb the objects to be detected.
[0117] Each branch pipe 53 is arranged in one-to-one correspondence with a carrier 1, and multiple branch pipes 53 are connected in parallel to the main pipe 52. The design of the branch pipes 53 needs to ensure that the negative pressure airflow can be evenly distributed to the second air channel 23 of each carrier 1 to achieve a stable negative pressure adsorption effect.
[0118] In some embodiments, Figure 3 As shown, each of the multiple branch pipes 53 is provided with a valve body 54 , and the valve body 54 is used to control the connection or disconnection of the branch pipe 53 .
[0119] In this embodiment, multiple branch pipes 53 are connected in parallel and are provided with a valve body 54. When the negative pressure of one or more branch pipes 53 is destroyed, the valve body 54 can be used to control the branch pipe 53 to be disconnected from the main pipe 52, thereby reducing the impact on other branches.
[0120] When the object to be detected needs to be adsorbed, the control system puts the valve body 54 on the corresponding branch pipe 53 in a connected state, and the negative pressure airflow enters the second air channel 23 of the carrier 1 through the branch pipe 53, and the object to be detected is tightly adsorbed on the carrier 1. When the object to be detected needs to be released, the control system puts the valve body 54 on the corresponding branch pipe 53 in a disconnected state, cutting off the passage between the negative pressure airflow and the second air channel 23 of the carrier 1, and the object to be detected can be easily removed.
[0121] In this embodiment, since each carrier 1 corresponds to a branch pipe 53 and a valve body 54, multiple carriers 1 can work simultaneously and perform parallel detection. At the same time, since each valve body 54 can independently control the connection or disconnection state of its corresponding branch pipe 53, the negative pressure adsorption of a single carrier 1 can be independently controlled to meet different detection requirements.
[0122] For example, the valve body 54 may be a logic control valve, a vacuum logic determination valve or other solenoid valve.
[0123] When one of the branches is abnormal, the valve body 54 can automatically make a logical judgment and disconnect the vacuum to protect the vacuum of other branches from being destroyed.
[0124] In some embodiments, the detection platform also includes a negative pressure controller, one path of the negative pressure generator 51 is connected to the main pipe 52, and one path of the negative pressure generator 51 is connected to the negative pressure controller. The negative pressure controller can display the negative pressure status of the detection platform, and the staff can adjust the negative pressure suction by inputting into the negative pressure controller.
[0125] In some embodiments, Figure 6 As shown, each of the multiple carriers 1 is provided with a target 13, and the target 13 may be a light emitting diode (LED) array, a reflective mark or other patterns or structures that can be recognized by an imaging device.
[0126] The design of the target 13 needs to ensure that it has sufficient recognition and contrast under the viewing angle of the imaging device so that the imaging device can accurately detect the position and posture of the carrier.
[0127] The multiple targets 13 are used to cooperate with the imaging device to detect the positions and postures of the multiple carriers 1.
[0128] The imaging device may be an image acquisition mechanism on the detection device. The imaging device (such as a camera) is used to capture an image of the target 13 and transmit the image data to the control system. The imaging device needs to have sufficient resolution and frame rate to track the movement of the target 13 in real time and accurately reflect the position and posture of the carrier 1.
[0129] The detection platform also includes a controller, which is used to connect with the imaging device to control the multiple platforms 1 to be in a correct posture.
[0130] The controller is used to connect with the imaging device, and the controller can receive image data from the imaging device and analyze the position and posture of the target 13 through an image processing algorithm. According to the analysis results, the controller sends a control signal to the rotation drive mechanism 2 of the carrier 1 to adjust the position and posture of the carrier 1 to achieve a preset accurate state.
[0131] In this embodiment, a target 13 is attached to each carrier 1, which can be used to dynamically monitor the state of the adsorption block 11. For example, the state of the adsorption block 11 includes abnormal states such as step loss and position deviation, and can also be used for dynamic compensation.
[0132] In some embodiments, Figure 1 As shown, the detection platform also includes: a height card 61. Before the platform 1 is loaded with materials, the height card 61 is suitable for covering the top of multiple platforms 1. The gap or contact state between the top of the platform 1 and the height card 61 is used to detect whether the multiple platforms 1 are at the same height.
[0133] Loading is performed when multiple carriers 1 are at the same height; when a certain carrier 1 is higher or lower, the height of the target carrier 1 can be adjusted by adjusting the installation position of the adjusting mechanism 4 on the output shaft 211 of the rotating drive mechanism 2.
[0134] Exemplarily, the height card 61 may be a hard plate extending along the arrangement direction of the plurality of carriers 1 , or may be a laser rangefinder, an infrared detector or a displacement sensor.
[0135] After adjusting the height of the carrier 1, the height clamp 61 is used again for detection. The above steps are repeated until all carriers 1 are at the same height and meet the detection requirements.
[0136] In some embodiments, Figure 3 and Figure 4 As shown, the detection platform further includes: a retaining member 62 and a bearing 63 .
[0137] The retaining member 62 is provided with a plurality of mounting positions, the carrier 1 is passed through the mounting positions, the plurality of carriers 1 are arranged in one-to-one correspondence with the plurality of mounting positions, a plurality of bearings 63 are provided, and a bearing 63 is provided between the retaining member 62 and the carrier 1 .
[0138] The bearing 63 is located between the holder 62 and the stage 1, and mainly plays the role of reducing friction, reducing wear and improving rotation flexibility. In the detection stage, the presence of the bearing 63 enables the stage 1 to move and adjust its position more smoothly, thereby improving the detection efficiency and accuracy.
[0139] According to actual needs and application scenarios, different types of bearings 63 can be selected, for example, sliding bearings 63, rolling bearings 63, etc. Sliding bearings 63 are suitable for low-speed and heavy-load applications, while rolling bearings 63 are more suitable for high-speed and light-load applications.
[0140] In this embodiment, the solid structure of the holder 62 and the supporting function of the bearing 63 improve the stability of the rotation of the stage 1 during the detection process and reduce the error caused by friction and wear. Each stage 1 is radially restricted by the bearing 63, so that the overall runout can be within 0.05, and the accuracy meets the optical detection requirements.
[0141] In some embodiments, Figure 2 As shown, the detection platform also includes: a frame 64 and a light shielding plate 65.
[0142] The rotary drive mechanism 2 and the negative pressure assembly 5 are both connected to the frame 64 , and the frame 64 supports and fixes the rotary drive mechanism 2 and the negative pressure assembly 5 .
[0143] The shading plate 65 is arranged at the top of the frame 64 along the first direction. When the product 7 to be inspected is photographed and inspected, the shading plate 65 can block the contour lines of the structure such as the frame 64, the carrier 1, and the rotating drive mechanism 2, thereby reducing interference with the imaging of the product 7 to be inspected and improving the inspection results.
[0144] The shading plate 65 is usually made of a material with good shading performance and stable mechanical properties. For example, the shading plate 65 can be a black metal plate, a plastic plate, or a glass plate with a shading coating.
[0145] The carrier 1 passes through the light shielding plate 65 and protrudes out of the light shielding plate 65 along the first direction, so that products 7 to be inspected in multiple sizes can be inspected.
[0146] In some embodiments, the detection platform further includes a protective cover 66 , which is disposed outside the negative pressure component 5 and can protect the negative pressure component 5 .
[0147] The protective cover 66 is provided with an escape position, which is used to escape the terminal box 67 so as to facilitate the electrical connection between the detection platform and other electronic device plug-in terminals of the detection equipment.
[0148] In some embodiments, the detection platform further includes a wiring member 68, which is disposed on one side of the detection platform. The wiring member 68 is used to fix and guide the wiring harness to reduce the difficulty of wiring arrangement.
[0149] An embodiment of the present application also provides a detection device, comprising the detection platform of any of the above embodiments.
[0150] According to the detection device provided in the present application, by setting up a detection platform, the detection platform forms the platform 1, the deformable connection mechanism 3, the adjustment mechanism 4 and the output shaft 211 of the rotating drive mechanism 2 into a whole. During the rotation of the output shaft 211 of the rotating drive mechanism 2, the platform 1, the deformable connection mechanism 3 and the adjustment mechanism 4 rotate synchronously, and the first airway 15, the deformable connection mechanism 3 and the second airway 23 rotate synchronously. The deformable connection mechanism 3 can absorb the stress generated by the height change or rotation of the platform 1 and the output shaft 211 of the rotating drive mechanism 2, thereby improving the airway sealing and the stability of the connection, avoiding the phenomenon of trachea winding, and reducing the risk of air leakage.
